Parameter Comparison

Engineering Selection Recommendations

A3C-2P-2DSA(30) - Hirose Electric Co Ltd

This part is the direct equivalent substitute for the obsolete A3C-2P-2DSA. It maintains identical electrical and mechanical specifications with the exception of packaging (Bulk vs. standard) and product status (Active). The A3C-2P-2DSA(30) carries RoHS Compliant certification, providing regulatory advantage over the original obsolete part. This is the primary recommended substitute for direct replacement applications.

MTMM-101-03-F-D-150 - Samtec Inc.

This cross-manufacturer substitute meets all critical dimensional and electrical requirements. The MTMM-101-03-F-D-150 features an extended operating temperature range (-55°C ~ 125°C) and higher current rating (3A), providing enhanced performance margins. The cuttable header design offers additional application flexibility. Contact length variations are within acceptable mechanical envelope tolerances. ROHS3 Compliant certification is provided. This substitute is suitable for applications requiring higher thermal or current performance.

TMM-101-06-S-D - Samtec Inc.

This cross-manufacturer substitute meets all critical dimensional and electrical requirements with the highest current rating (3.2A per Contact) and extended operating temperature range (-55°C ~ 125°C). The longer post length (0.192" / 4.88mm) accommodates deeper PCB mounting applications. ROHS3 Compliant certification is provided. Material flammability rating is not specified for this part. This substitute is suitable for applications requiring maximum current capacity or extended post length.

Frequently Asked Questions (FAQ)

Q: Can A3C-2P-2DSA(30) be used as a direct replacement for A3C-2P-2DSA?

A: Yes. The A3C-2P-2DSA(30) is the direct equivalent with identical electrical and mechanical specifications. The primary difference is product status (Active vs. Obsolete) and packaging format (Bulk). Both parts maintain the same 2-position, 2-row configuration with 0.079" (2.00mm) row spacing, through-hole solder termination, and push-pull fastening.

Q: What are the key differences between Hirose and Samtec substitutes?

A: The Hirose A3C-2P-2DSA(30) maintains exact dimensional and material specifications of the original part. Samtec substitutes (MTMM-101-03-F-D-150 and TMM-101-06-S-D) offer higher current ratings (3A and 3.2A respectively), extended operating temperature range (-55°C ~ 125°C), and different insulation materials (LCP vs. Polyamide). Contact lengths and post lengths vary between Samtec options.

Q: Are there mechanical compatibility concerns with Samtec substitutes?

A: Samtec substitutes maintain the critical 0.079" (2.00mm) row spacing and 2-position, 2-row configuration. However, insulation height differences (0.059" for Samtec vs. 0.035" for Hirose) and overall contact length variations must be evaluated against specific PCB layout and mating connector specifications. The MTMM-101-03-F-D-150 has a 0.150" mating contact length versus 0.138" for the original; TMM-101-06-S-D has 0.126" mating contact length.

Q: Do all substitutes meet the original voltage and current requirements?

A: Yes. All substitutes meet or exceed the original 200V voltage and 1A current requirements. Samtec options provide higher current ratings (3A and 3.2A), which represent performance enhancements rather than limitations.

Q: What is the significance of the cuttable header feature on MTMM-101-03-F-D-150?

A: The cuttable header design allows the connector to be segmented for custom position configurations. This feature provides application flexibility but does not affect compatibility with standard 2-position mating applications.

Q: Are all substitutes RoHS compliant?

A: A3C-2P-2DSA(30) is RoHS Compliant. Both Samtec options (MTMM-101-03-F-D-150 and TMM-101-06-S-D) are ROHS3 Compliant. The original A3C-2P-2DSA does not specify RoHS status.

Q: Which substitute is recommended for new designs?

A: For direct replacement of existing A3C-2P-2DSA applications, A3C-2P-2DSA(30) is recommended due to identical specifications and active product status. For new designs requiring enhanced performance, Samtec options provide higher current capacity and extended temperature range. Selection should be based on specific application requirements for current, temperature, and mechanical envelope constraints.
